1G crankcase and oil residue as hard as stone

[NeSo]

Hallo as u can see I am building 4g63 engine , an i have checked a lot of videos from YT with crankcase and didn’t see any engine having this , I can only get it out with hammer and flat screwdriver hitting it , I tried dremel and it didn’t help much , does any one know how to clean it good ? I can’t get everywhere with screwdriver , was it from bad oil ? I bought only engine cause I am swapping it from 4g37

Make sure you’re ready to blow it dry with air then wipe it down good and put some atf on the machined surfaces afterwards.

Try oven cleaner. Gets baked on stuff to loosen up. I used it on my Saturn motor but it was all aluminum. Just MAKE SURE you wash it all out thoroughly afterwards and lube as per the advice given above.
